The characteristic of sepal shape in a flowering plant is controlled by one gene on Chr I and another two genes on Chr 4. Based on this information alone, the sepal shape trait can be described as what

If a gene of interest were cloned into pUC18 at the lacZ multiple cloning site before transformation, what would be selected to have the best chance of obtaining a clone that contains the insert of interest

PCR followed by gel electrophoresis

CaCl2

A lawn of bacteria

A scientist forgot to add ampicillin to the plate to select for colonies containing pUC18 (contains AmpR and lacZ). What would the scientist observe on the plate assuming the transformation was done correctly
